Employees of the Security Service of Ukraine, together with the Prosecutor's Office of the Autonomous Republic of Crimea, have disclosed the activities of a network of media structures controlled by the Russian Federation and conducting investigative actions in the office of RIA Novosti-Ukraine in Kyiv.

"Law enforcers have determined that they were used by the aggressor country in the context of a hybrid information war against Ukraine. And now investigative actions are being carried out," spokeswoman of the SBU Olena Hitlianska told Interfax-Ukraine on Tuesday morning.

She specified that, in particular, searches are taking place in the office of RIA Novosti-Ukraine located in the center of Kyiv.

According to Hitlianska, law enforcers also detained Kiril Vyshynsky, an employee of RIA Novosti-Ukraine, in Kyiv on Tuesday morning.
